these muscle groups either extend a joint, extensors) or contract the joint (flexors). triceps extend the elbow joint, biceps bend the elbow joint.
Muscles that bend a joint are flexors; musces that straighten a joint are extensors.
There are flexors and extensors in the forearm and they control the movements of the hand and wrist. If you hold your hand out (with the palm down), the flexors allow your hand to bend downward. The extensors allow your hand to bend upward.
No, it is the opposite. Muscles that bend a joint are called flexors, while muscles that straighten a joint are called extensors. For example, the biceps are flexors of the elbow joint, and the triceps are extensors of the elbow joint.
a muscle that extends or straighten a limb or body part is called extensor
Any flexor muscle decreases the angle of a joint. When you flex your biceps brachii, the distance between your forearm and arm becomes closer together. When you use your extensors on the same joint, your arm will straighten.
The agonist muscle for wrist flexion is the flexor carpi radialis, while the antagonist muscle is the extensor carpi radialis longus. These muscles work in opposition to produce movement at the wrist joint.
Skeletal muscles are found in pairs called flexors and extensors. The flexors bend a joint, and the extensors straighten the joint. Muscles cannot push; they only pull.
If both the flexors and extensors contracted simultaneously there would be no movement in the muscle whatsoever.
There are around 20, collectively called the flexors and extensors.
